GSP Posts Letters Detailing VADA Testing Results on Twitter

Long-reigning UFC welterweight champion Georges St-Pierre has been adamant about undergoing strict drug testing for his upcoming UFC 167 title bout against Johny Hendricks, and it looks like he's put his money where his mouth is.

This morning, "Rush" posted two letters he received from Voluntary Anti-Doping Association (VADA) president Margaret Goodman—one dated October 3, the other November 1.

Both indicate his ongoing participating in VADA random drug testing for performance-enhancing drugs.

GSP notes that he has been tested by the VADA lab three times since September 1 for "the anabolic steroids panel, Carbon Isotope Ratio (CIR/IRMS) tests for the presence of exogenous testosterone, and analysis to determine erythropoietin (EPO) and human growth hormone (hGh) administration," the letters say.

St-Pierre and Hendricks ended up exchanging a back-and-forth war of words in the media since neither side could agree on the drug testing terms for their November 16 title tilt, per ESPN.

For the record, neither GSP nor "Bigg Rigg" have ever failed a drug test in 42 combined professional mixed martial arts contests, despite being two of the biggest, strongest competitors at 170 pounds.

Hendricks enters the heavily-anticipated pay-per-view matchup on the strength of a six-fight win streak, while the Tristar gym standout looks to make it nine title defenses in a row (and 12 straight wins).

Will Hendricks' powerful left hand manage to find the French-Canadian superstar's chin, or will the GSP's refined boxing and wrestling, once again, just be too much to handle?
